Definitions
- This invention relates to the use of D-tagatose as a pre ⁇ biotic component. It can be used as a prebiotic food, food additive or food supplement.
- Tests have surprisingly shown that oral intake of the un- absorbable carbohydrate, D-tagatose, induces production of butyrate in colon. From the literature it is known that butyrate possibly has a colon cancer protective ef- feet. Further, tests have shown that oral intake of D-tagatose stimulates the growth of beneficial lactoba- cilli and lactic acid bacteria in the human colon. There ⁇ fore, D-tagatose is useful as a prebiotic food to stimu ⁇ late the growth of beneficial bacteria and to induce the production of butyrate. Such prebiotic food is thus presumably useful for normalizing the bacterial flora in the colon and for preventing the risk of colon cancer in human beings.
- D-tagatose is a well-known keto-hexose which is useful as a reduced-calorie food sweetening and bulking agent, and as an additive in detergent, cosmetic and pharmaceutical formulations.
- U.S. Patents Nos. 5,002,612 and 5,078,796 to Beeadle et al. teach processes of making D-tagatose by isomerizing a mixture containing D-galactose with a metal hydroxide in the presence of a catalyst at a relatively low temperature to form an intermediate complex, followed by neutralization with acid to yield D-tagatose.
- D-tagatose is known as an anti-hyperglycaemic agent that can be used to inhibit formation of advanced glycosyla- tion in products in mammals, as described in U.S. Patents 5,356,879 and 5,447,917 to Zehner et al .
- D-tagatose also is known as a low-calorie carbohydrate sweetener and bulking agent that can be used in the preparation of sweetened edible formulations in stead of sucrose, as taught in U.S. Patent 4,786,722 to Zehner.
- the mucosal surfaces of the intestinal tract are amongst the main sites of cell replication in the human body.
- the epithelial cells are exposed not only to the circulation and to the endogenous secretions of other mucosal cells, but also to the contents of the colonic lumen which is rich in food residues and the metabolic products of the micro flora.
- I. T. Johnson “Butyrate and markers of neoplastic change in the colon", European Journal of Cancer Prevention, Vol. 4, 1995
- Epidemiol- ogical and animal studies suggest that dietary fat and protein may promote carcinogenesis in the colon, whereas increases in fibre and complex carbohydrates in the diet may protect against colon cancer.
- Colonic luminal bu ⁇ tyrate concentrations are postulated to be the key pro ⁇ tective component of high-fibre diets against colon can- cer (O.C. Velazquez, H.W. Lederer and J.L. Rombeau 1996. "Butyrate and the Colonocyte: Implications for Neopla- sia", Digestive Diseases and Science Vol. 41, No. 4: 727- 739) .
- Butyrate is one of the short-chain fatty acids (SCFA) , i.e. the C2-5 organic acids. These compounds are formed in the gastrointestinal tract of mammals as a result of anaerobic bacterial fermentation of undigested dietary components, and are readily absorbed by the colonic epi- thelium. Dietary fibre is the principal substrate for the fermentation of SCFA in humans, however, intake of fibres is often low in a typical western diet. Other undigested components, like starch, proteins, contribute to the production of SCFA, but also low-molecular weight oligosac- charides, sugars, and polyols, which escape digestion and absorption in the small intestine, contribute to the production of SCFA.
- SCFA short-chain fatty acids
- acetate, propionate, and butyrate account for at least 83 c of SCFA and are present in a nearly constant molar ratio 60:25:15 (Velazquez et al . , supra).
- the colonic epithelium is a dynamic tissue in a state of continual renewal. Cells proliferate in the lower two- thirds of the normal colonic crypt, and cease dividing as they migrate further up the crypt. The continuous movement of cells up the colonic crypt is tightly linked to differentiation (A. Hague, A. J. Butt and C. Paraskeva 1996 "The role of butyrate in human colonic epithelial cells: An energy source or inducer of differentiation and apoptosis", Proceedings of the Nutrition Society 55:937-
- lactobacilli are important inhabitants of the intestinal tract of man and animals. Lactobacillus species, notably Lactobacillus acidophilus, are most often impli ⁇ cated in assisting the establishment of a 'normal micro flora', especially following antibiotic therapy. In addition, probiotic lactobacilli have been implicated in a variety of beneficial roles, including (T. R. Klaenhammer 1998, "Functional activities of lactobacillus probiotics: Genetic mandate", Int.
- probiotic bacteria A lot of studies on probiotic bacteria have shown that it is very difficult for these bacteria to colonize the hu ⁇ man colon, that is after having stopped supply of pro ⁇ biotic bacteria in the diet, they disappear from faeces. This makes it more obvious to isolate possible probiotic bacteria from the human intestine (U.S. Patent 5,709,857) . It is even more obvious to selectively feed the lactobacillus already present in the colon (prebiotic concept) .
- D-tagatose is a naturally-occurring keto-hexose which only differs from D-fructose at the fourth carbon atom.
- the rather small difference has big implications on the overall metabolism of D-tagatose, as only 15-20% of ingested D-tagatose is absorbed in the small intestine.
- the major part of ingested D-tagatose is fermented in the co ⁇ lon by indigenous micro flora resulting in production of short-chain fatty acids (SCFA) .
- SCFA short-chain fatty acids
- D-tagatose Being a potential future food ingredient with a sweetness similar to sucrose, D-tagatose is an ideal ingredient for application in a range of food products.
- the ideal fer ⁇ mentation products of D-tagatose with a high proportion of butyrate and stimulation of growth of lactobacilli make D-tagatose an ideal future prebiotic food ingredient that keeps a healthy balance in the colon and may have even a cancer protective role.
- the invention relates to use of D-tagatose as a prebiotic food , food additive or food supplement.
- D-tagatose has been shown to induce production of butyrate by bacteria in the human colon and to stimulate growth of lactobacilli and lactic acid bacteria in the human colon. This makes D-tagatose a possible candidate for the production of a drug for preventing colon cancer.
- D-tagatose can be taken orally in an effective amount to induce production of butyrate in the human colon and/or to stimulate the growth of lactobacilli and lactic bacte ⁇ ria in the human colon. Such amount will normally be 5 to 30 gram, and preferably 5 to 15 gram a day taken 1-3 times a day. D-tagatose can be taken in any normal food product, such as confectionery, chewing gum, ice cream, dessert, soft drink, breakfast cereal, yoghurt, health drink or health bar. It has been proposed to substitute sucrose or to sweeten such products using D-tagatose.
- D-tagatose as such, for example as a sweetener in coffee, tea or the like, or to take it as it is or in a formulated form, such as tablets.
- the amounts effective to achieve the useful effects according to the invention are the same as normally used to sweeten food products and/or to give them the normal bulk effect.
- Fig. 1 shows the concentration of butyrate in various gastrointestinal sections.
- Fig. 2 shows the 12 hour in vi tro production of bu ⁇ tyrate in the content from different gut sec- tions.
- Fig. 3 shows the total 12 hour in vitro production of SCFA.
- Fig. 4 shows the butyric acid absorption in the blood.
- Fig. 5 shows the influence of D-tagatose on bacterial composition in human faeces.
- one group of 8 pigs was having a standard diet + 15% sucrose (unadapted) , and another group of 8 pigs was fed a standard diet +5% sucrose + 10% D-tagatose (adapted) for 17 days.
- Table 1 shows that colon content from adapted pigs fer- ments D-tagatose in a very special way with low acetate and high butyrate and valerate, whereas the colon content from unadapted pigs gives a rather normal SCFA profile with less than 20% butyrate and a high proportion of acetate.
- the overall fermentation rate measured as rate of degradation of D-tagatose, is low in in vi tro incubation with D-tagatose in unadapted pigs, 1.1 g of D-tagatose pr hour pr kg digesta versus 15.3 g of D-tagatose pr hour pr kg digesta in adapted pigs.
- 3 groups of each 2 pigs were having a standard pig diet + 20% sucrose, a standard pig diet + 10% sucrose + 10% D-tagatose, and a standard pig diet + 20% D-tagatose for 33 days.
- the pigs were killed on the 33. day 6 hours after morning feeding, and the entire gastrointestinal tract was divided into 8 segments.
- Fig. 1 shows the concentration of butyrate in the various gastrointestinal sections at the time of slaughtering. The results clearly indicate that butyrate is present only in the hind gut, as expected, and that butyrate is increasing in a dose response manner to the intake of D-tagatose .
- Fig. 2 shows that the 12 hour in vi tro production of bu- tyrate similarly is acting in a dose response manner to the intake of D-tagatose in the diet.
- Col colon section 1
- Co2 colon section 2 Rec 0 rectum
- Fig. 3 shows the total 12 hour in vi tro production of SCFA in the gut, that is the in vi tro production rate of SCFA multiplied by the amount of gut material in the various sections.
- the data presented here are normalized to production of SCFA pr kg feed.
- the in vi vo absorption of SCFA in the blood is measured by taking blood samples simultaneously from 3 catheters in Vena Mesenterica, Ateria mesenterica and Vena Porta over a 12 hour period after the morning feeding.
- the absorption is measured in the same 5 pigs at 3 different occasions, that is after 7 days adaptation to standard pig diet + 20% sucrose (sucrose) , the first day of switching to a standard pig diet + 20% D-tagatose (unadapted) , and after 7 days adaptation to a standard pig diet + 20% D-tagatose (adapted) .
- the concentration of SCFA's is determined in samples from the portal vein, that is the blood stream leading from the digestive system to the liver, and in the arterial blood, that is the blood stream before the digestive system.
- the difference between the two integrated by time is a measure of the intestinal absorption of SCFA's.
- Fig. 4 shows the concentration of butyrate in the portal vein and in the arterial blood as a function of time af- 13
- the area between the 2 curves is equal to the total absorption of butyrate from the intestine.
- the concen- tration of butyrate in the portal vein is low and stable over time and very low in the arterial blood, indicating that the absorbed butyrate is cleared by the liver.
- the amount of butyrate in the portal vein is gradually in- creasing over the 12 hours of measuring.
- the concentration of butyrate in the por ⁇ tal blood shows a very steep increase a few hours after feeding, and also the concentration in arterial blood is increasing, indicating that the liver is no longer able to clear the portal vein absorbed butyrate.
- the total absorption of butyrate represented by the area between the 2 curves does not differ in the adapted and unadapted state .
- the in vi vo absorption of butyrate in the portal vein does not directly reflect the production of butyrate in the colon. Under normal conditions a great part of the produced butyrate is utilized by the colonic mucosa before entering the blood. The very large in vi vo absorption of butyrate merely reflects a production of butyrate in the colon that far exceeds the utilisation by the mucosal cells.
- the amount of SCFA produced by D-tagatose is calculated as the amount produced in the assay with 1% D-tagatose added subtracted by the amount produced in the assay without D-tagatose. Further, the delivered faeces samples were tested for content of various intestinal bacteria counts by spreading on selective media.
- Table 2 shows the mol% of the various SCFA produced in vi tro by D-tagatose in the unadapted and adapted state, and also the actually produced total SCFA in mmol pr 1 of incubation slurry.
- SCFA The production of SCFA is 8.8 mmol/1 and 24.3 mmol/1 after 4 hours of incubation in the unadapted and adapted state, respectively.
- the ratio of butyrate after 4 hours of incubation is also higher in the adapted state and much higher than the normally observed 15-20%. After 48 hours of incubation there is no longer any difference in the amount of SCFA produced, and the proportion of butyrate is high both in the adapted and unadapted incuba- 1 6
- Fig. 5 shows the results of counting bacteria (log scale) on different selective media.
- the number of lactobacilli and lactic acid bacteria is increased in number, and en- tero-bacteria is decreased in faeces of human volunteers ingesting D-tagatose for 14 days compared to the same persons not ingesting D-tagatose.
- LAC lactobacilli
- Bac bacteroides
- Bif bifidobacteria
- D-tagatose is a rather rare sugar for intestinal bacteria and is only fermented by a limited number of genera of bacteria, enterococci, lactobacilli, and obviously some butyrate producing intestinal bacteria.
- Other fibres or undigested carbohydrates are either not a substrate for butyrate producing bacteria, or competition for the de ⁇ livered substrate favours growth of other bacteria.
- a reasonable explanation for the butyrate inducing effect of D-tagatose is that butyrate producing bacteria is fa- voured over most other bacteria when supplying D-tagatose.
- D-tagatose pr day aiming at a pre-biotic effect is very easily achieved as D- tagatose can be incorporated in almost any food, but most obviously in applications as a substitute for sucrose, for example , as mentioned, in confectionery and chewing gum, ice cream and other desserts, yoghurts, cereals and energy bars, soft drinks and health drinks.
